I wouldn't conclude that he's necessarily a weak rush defender as a 3-4 OLB.
As a 260 lb 4-3 DE lined up opposite a 300+ lb OT, Burgess is going to be run at directly a lot in running downs, but should be effective in pursuit and of course have the advantage when pass rushing.
As a 260 lb 3-4 OLB, Burgess should hold the corner well against blocking but might see plays get outside of him sometimes. He might also be liability in early down pass coverage when the scheme requires him to drop back. In passing downs, he'll usually be a rushing down lineman, just like in a 4-3.
He's actually an almost perfect size for a 3-4 OLB; the question is if he has the agility to cover and tackle in space when it's required. And of course can he stay healthy.
